Question 1

What precautions should be taken regarding Cam Gear and Timing Belt during the replacement procedure on Volkswagen Jetta?

Accepted Answer

This procedure should be done with caution because the rotating of crankshaft or the camshaft alone with the timing belt released may damage the valves, a minimum of rotation of the camshaft is only necessary to make sure that the marks of the sprockets match with the rear timing belt cover. The battery has to be disconnected by re-educating oneself on a number of systems to work with. This is a procedure that can be used on the 2.0L (CBPA) and 1.4L (CZTA, DGXA) engines. The complexity of the timing system requires a lot of experience; any error may cause serious damage to the engine, and it is better to use the services of a specialist in this case. See that contact points of timing belt components are not oiled to ensure they do not fail prematurely. Start by unscrewing the negative battery cable, unscrewing the wheel bolts on the right-front, lifting the vehicle high enough, and removing the right-front wheel. Take off the splash shield, inner fender liner on the driver side and label the direction of rotation of the drive belt and remove it together with the spark plugs. Once the locking pin of tensioner is removed, place the engine at TDC position and take off coolant expansion tank, air filter housing, turbocharger pipes, and disconnection fittings of fuel hose. Detach retaining clips, upper timing belt cover, crankshaft pulley and lower cover fasteners. When using a timing belt again, indicate its direction of movement. Its timing belt is easily removed by lifting the tensioner but not bending it sharply. With the 2.0L, make certain that the crankshaft is at TDC, hold the engine and lift off the passenger side engine mount and bracket. A wrench is used to avoid crankshaft rotation when loosening the retaining bolts of the pulley. Check the tensioner pulley and idler wheel on the timing belt to ensure it works properly and examines the belt to confirm that it is not contaminated or worn out. In case of a good belt, it should be fitted back in the same position. Change the belt in case of concern about the state of it or possibility of a surpass of 60,000 miles. Prior to fueling the engine, turn the crankshaft by hand to confirm resistance that is an indication of a problem. On the 1.4L engines, be sure the crankshaft is set at TDC, replace any components removed and make sure the timing belt runs correctly around the sprockets noting rotation marks. With the 2.0L engines, make sure that the mark of the camshaft sprocket is properly aligned, loop the timing belt, and also ensure that all the timing marks are at TDC. Tension the belt, and verify that everything is in line after two full revolutions of the crankshaft, and it is important to note that the procedure should be reversed in order to reassemble.

Question 2

What precautions should be taken with the cam gear and timing belt when rotating the crankshaft or camshaft for V6 engines on Volkswagen Passat?

Accepted Answer

One should exercise caution since turning the crankshaft or camshaft alone when timing belt has been taken off may be damaging the valves; it should only be gently turned to the timing belt position to adjust the camshaft alignment tool. This procedure needs two special tools, and they should be procured in advance. It is illustrated with the help of a DOHC engine but the stages are the same with SOHC engines with certain differences in the appearance of the parts and the places of the fasteners. Timing mechanism is complicated and errors may cause some serious engine damage hence only those who have done this before are supposed to engage in this process. Unplug the negative battery connection, being sure to have the anti-theft radio code, and keep in mind that disconnection of battery can lead to driveability problems and warning signals. Lift the vehicle safely, take off the lower splash shield and place the radiator support panel in order to have access to the engine. Lift the engine cover, spark plugs, and any other parts that are required such as the cooling fan and power steering pump pulley. Unscrew the timing belt covers, TDC rotate engine and attach TDC locking tool. Take off the crankshaft pulley and timing belt lower timing belt cover and make a mark on the timing belt (unless it is being replaced). Unscrew the position of the tensioner of the timing belt and take the timing belt off. Loose the camsprockes so they can swing freely and in case of necessity, remove the crank sprocket. Check the timing belt and other parts to be sure they are not worn out or contaminated and install new damaged parts. Check the crankshaft during installation by giving it a hand turn so as to detect any resistance, which is a sign of complications. Install any sprockors that were removed and make sure that they are rotating freely and loop the timing belt under crankshaft sprocket and connect it correctly. Tension the belt based on the type of engine and follow up on the appropriate tension and alignment before completing the installation of all the parts in the reverse order.
